High Efficiency Dust Scrubbers for Continuous Miner in Underground Mines

Based on the experimental data by a full scale test model and the relevant existing achievements, four new concepts of group dust scrubbers were designed in the paper. The new dust scrubbers consist of two to four common dust separators in series: wet fan, wet Venturi and foam filter bed. Wetting and foaming agents are used to increase the efficiency of dust separation. High efficiency is not required for each part of the group dust scrubbers, but the whole system has a high working reliability. All parts of the group dust scrubbers have the most suitable separating efficiency for different size and concentration of dust particles in airflow, according to their technical features. Four group dust scrubbers have a high efficiency from 94.4% to 99.7% for separating respirable dust at a rational cost.

惰粉流化床协同分离消失模等黏性烟尘的除尘新方法研究

创造性地把惰性粉剂流化床植入脉冲过滤除尘器中,使惰粉在脉冲喷吹清灰后,在线地预涂滤芯表面,隔离和过滤黏性气溶胶烟尘,尤其在消失模和树脂砂铸造高效除尘上有着广阔应用前景。惰粉鼓泡流化床对黏性烟尘的循环调质和分层属性使得惰粉得到充分使用,如此脉冲喷吹过滤器对消失模气化等黏性气溶胶烟尘的长效除尘成为可行。阐述了该除尘新方法的模型和运行机理,并对黏性聚团颗粒鼓泡流化床的属性,惰性粉剂碳酸钙的选型以及耗用量等计算做了有效的研究。
